Jumper Cable and Jumper Wire
In a sense, Jumper cable and Jumper Wire is the same thing. However, as their different name indicates, there are still some slightest differences. Jumper Cable is a bit more complicated than Jumper Wire, and has more application range than Jumper wire. Jumper Cable can have multiple wires inside, and has insulation on each layers. The wire inside Jumper Cable is made of good conducts like aluminum, copper or even silver to deliver current or signal. On the other hand, Jumper wire is mostly used to indicate the wire used for connection of two distant points between adjacent components or in a breadboard.

Definition |
single conductor |
two or more conductors |
|
Uses |
To bear mechanical loads, to carry electricity and telecommunications signals, heating, jewelry, clothing, mesh, automotive or industrial manufactured parts, pins, needles, fish hooks, bulbs. |
Power transmission, to carry electricity and telecommunications signals. |
|
Types |
Solid wire, and stranded wires |
Twisted pair cable, coaxial cable, multi conductor cable and fiber optic cable. |
|
Advantages |
Solid wires are perfect for use in higher frequencies, offer low resistance. Stranded wire shows higher resistance to metal fatigue. |
Higher strength, heavy duty, insulated. |
Jumper Cable and Feeder Cable
Technically speaking, Jumper Cable is a special kind of Feeder cable. Only feeder cable is longer and wider, and their range of application is different.
Jumper cable is mostly a short 1/2 cable that connects one device to another device, like main feeder and antenna, feeder and BTS equipment. Not all Jumper Cables are electrical (Optical Jumper cable).
Feeder cable is mainly used to transmit RF signals. It is commonly used as coaxial RF cable for BTS equipment to feed RF signal to antenna. This requires the feeder cable's attenuation to be minimum. Moreover, its impedance should be as close as possible to the output impedance of the transmitter and the input impedance of the antenna.
